WILLIAM R. BOWMAN, OF DANVILLE, KENTUCKY.

THlLL-COUPLING.

SPECIFICATION forming part of Letters Patent No. 319,186, dated June 2, 1885.

Application filed October 2, 1884. (No model.)

To aZZ whom it may concern.-

Be it known that I, WILLIAM R. BOWMAN, of Danville, in the county of Boyle, and in the State of Kentucky, have invented certain new and useful Improvements in Thill-Gouplings; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters of reference marked thereon, making a part of this specification.

My invention relates to improvements in thill-couplings, and is designed, objectively, to produce a device that may be readily at tached to an ordinary clip and prevent rattling.

The improvement consists, essentially, of a chair supporting a flexible bearing for the shaft-iron, and is illustrated in the annexed drawings, in which Figure 1 represents a plan view of the coupling; Fig. 2-, a section through the same; Fig. 3, a detail perspective of the chair, and Fig. 4 a detail perspective of a modification of the said chair.

A designates a clip of ordinary construction,such as is in common use and B,the shaftiron. The shaft-iron is secured between the wings O by a bolt or by a pin, D, having one end pointed and the other formed into extensions at right angles to the pin, one of which, E, has its end extended parallel to the said The chair is formed of a socket, F, upwardly-extending arms G, and a cross-piece, H. The said cross-piece extends across and on top of the rear of the wings G, and supports the chair, the arms G and socket F hanging behind the shaft-iron. A piece of rubber, I, or other flexible material, of proper conformity, rests in the socket F under the eye of the shaft-iron, and extends rearward between the arms G and against the front of the clip proper. This chair (shown in-Fig. 4) is used with a common bolt. In the other figures the piece His extended to one side, and carries a downwardly-extending L-piece, K, the lateral arm of which is preferably placed at an acute angle to the other arm. This lateral arm is secured to the socket F by connecting-pieces L. This latter chair is used with the pin D.

The chair, with its flexible seat, having been placed in the clip, the shaft-iron is inserted and the pin D passed through the eye thereof. The arm E is placed under the shaft-iron, and that on the other side of the pin passing in at the angle of the L. As the shaft-iron is lowered, it carries the arm E with it, turning the pin D till the opposite extension passes behind the longer arm of the said L, thus completely locking in the said pin, but still leaving it so that it can be quickly removed.

Having described the device, what I claim 1; As an article of manufacture, an independent attachment for thill-couplings, consisting of a socket or box and upwardly-extending arms resting between the wings of the coupling-clip, a cross-piece connecting the arms and resting on the said wings, and a flexible seat sustained in the said chair, substantially as and for the purpose specified.

2. As an article of manufacture, an independent chair-support for a flexible seat, said chair resting between and hung on the wings of a thill-coupling clip, substantially as and for the purpose specified.

3. A removable seat attachment for thillcouplings, consisting of a socket, upwardlyextending arms, an extended cross-piece, and an L-piece secured to one side of the chair a short distance from the same, substantially as and for the purpose specified.

4. In combination with a removable chair or seat attachment for thill-couplings, a pin for securing the shaft-iron to the clip, said pin having one end formed into right-angle extensions, one of which is bent so as to continue parallel to the pin, substantially as and for the purpose specified.

5. In combination with a thill-coupling, a chair consisting of a socket, arms, and crosspiece, and an L-extension, a flexible seat or hearing, and a pin having extensions at right angles to it on one end, one of the said extensions being bent so as to be parallel to the pin, substantially as and for the purpose specitied.

In testimony whereof I affix my signature, in presence of two witnesses, this 29th day of March, 1884.
